AUTOMATIC WEFT-REIE'LENISHING MECHANISM or .LOOMS.

Original application filed September 30, 1924, Serial No; 740,825, and in Great Britain November 27, 1922. Divided and this application filed July 17, 1925. Serial No. 44,3?5.

This invention relates to automatic weft replenishing mechanism for looms of the kind comprising a swivel adapted to actuate a transferrer and having means for preventing the swivel from so actuating the transferrer in the event of the shuttle not being properly positioned in the shuttle box.

The object of the present invention is to devise improved weft replenishing mechanism of the above character, and the invention consists in automatic weft replenishing mechanism for looms of the kind referred to comprising in combination a transferrer, a swivel for actuating the transferrer, a movable member carried bythe swivel and normally adapted to be positioned for moving the transferrer when the swivel is operated and means adapted to move said member so that the transferrer will be out of its path" in the event of the shuttle not being properly positioned in the shuttle box.

The invention also consists in the apparatus hereinafter described.

The accompanying drawings illustrate one mode of carrying out theinvention,

Figure l is a plan of a part of the mechanisin showing the tranferrer and mechanism associated therewith for actuating the same and for preventing actuation when the shuttle is not in its proper position.

Figures 2 and 3 are similar views showing the parts in different positions. and

Figure 4 is a side view of the transferrer and swivel.

In carrying my Invention into efiect 1n one convenient manner I may form my 'ransferrer somewhat in the manner de-' 4. scribed in the specification of my copending application No. 740,826, filed Sept. 30, 1.924, of which this application is a division, that is to say, of substantially L formation in plan comprising an arm 70 by which it is mounted on the transferrer shaft Z and at the end of which is the hammer or transferrer proper in" extending across the interior of the magazine in position to engage when depressed the lowermost cop in the magazine, the hammer is extending substantially at right angles from the arm is. The latter is provided with a shoulder or projection Fe with which engages a pin m, shaft or other projection upon the swivel m which is mounted eo-axially with the hammer so that when the swivel is depressed by the action of the feeler mechanism for Weft replenishing a hunter on the sley engages a projection on the swivel, and in its forward stroke thus rota-tes'the swivel (in the manner shown in Figure 4) causing the pin m thereon to engage with the shoulder or projection is upon the hammer inorder to rotate the latter for transfer of the cop. i Q g In order, however, that the transfer may not be eifected'unless the shuttle is properly positioned in the shuttle box I arrange the pin'or memberm upon the swivel'to be controlled by a spring n and provide means in connection therewith which will enable the spring to move the member so that the shoulder or projection 70 upon the hammer arm willbe out of the path of the member so that the hammer arm will not be actuated on rotation of the swivel. I

In the construction illustrated this is effected by'means of-afdetector comprising a longitudinally movable member 0 slidable in a bracket 79 secured to the breast beam and provided with an attachment 0 which holds the pin on upon the swivel in place against the action of its spring a, such detector either acting direct upon the pin or projection m or indirectly through the medium of a collar 9 which is secured by a to slip off.with loom vibration but when the swivel is depressed by the action of the'feeler motion as shown in Figure 3 the collar 9 is also rotated so thatthe detector attachment 0 retains only a very fine hold upon thecollar. If, however, the shuttle 1 is not properly positioned the nose 1" 'or some other part of the shuttle during the forward movement of the sley comes into contact with the end of the detector arm 0 thus moving the latter (if necessary against a suitable spring) and freeing its attachment 0' from the collar 9 in the manner shown in Figure 2 so that the spring it forces the collar along the hammer shaft and removes ie swivel pin or proiection on so that the ioulder i on the hammer arm will be out 01 its path and in consequence rotation of the swivel by the hunter on the sley will not actuate the transterrer. I

The parts, may he adapted to be subsequently properly positioned by hand or iii) Cir

of work which the loom may suitable autoi'natic means may be provided for the purpose. o. o w v t is to be understood that the Ioregoing details of construction are given by way of V illustration and not of limitationsince I say vary the form of transierrer hammer and the meansadopted tor actuating the "weit replenishing depending upon the class he called upon to execute or any practical requirements that may have to beiuliilled. v

Having now described my invention, what Let- V 11 claim as new and desire to secure by ters Patent is 1. In automatic welt replenishing mechanism tor looms or" the kind comprising a cop transterreroperated by a swivel actuated replenished, the

by. the sley when the weft is to be transterrer will be out of. its path in the event of the shuttlenot being properly posltionedinthe shuttle box, '2. Automatic weft replenish1ng1mechanism torlooms of the kind referred to com- 7 prising 1n combinat1on a transferrer, a

swivel for actuating said transferrer, a movable pin carried by said swivel and normally adapted to engage a projection upon the transferrer for operating theqsame when the swivel is rotated and means adapted to move 7/ said pin so that the transferrer will be out of its path in theevent of the shuttle not being properly positioned in the shuttle boX.

3. Automatic weft replenishing mechanism for looms ofthe kind referred to com I prising in combination a transferrer, a

swivel for actuating said transterrer, a movswivel combination of a cop trans-- *ferrena swivel mounted co-axially with momma able pin carried by the swivel so that normally it will engage a project on on the transferrer when the swivel is rotated, spring means for. moving the pin so that it will not en 'a e. with the transierrer means normally restraining said spring means from-operation and means releasing said spring restraining means in the event otthe shuttle not being properly positioned in the shuttle box.

4 Automatic weit replenishing mechanism for looms of the kind reterredto comprising in combination a transferrer, a

mounted cO-aXially with said transterrer adapted to be rotated by the sley, a p n movably carried upon said sw vel and adapted normally to engage a' projection on the transierrer m order to rotate thelatter tor replenishing weft and a detector actuated by the shuttle when the same is not properly positioned in the shuttle box to permit movement of said. pin so thatthe latterwill not engage with the transferrer. 5. Automatic weft replenishing mechanism for loomsofthe kind referred to comprising in combination :a transferrer, a swivel for actuating said trans terrer, a movable pin carried upon said swivel and normally adapted to engage a projection on the ,ti'ansierrer, a spring controlling said pin and a detector actuated by the shuttle when the latter is not properly positioned in the shuttle box to permit'the spring to function ,to remove the pin so that it will not engage the transferrer. x

6. Automatic wettfreplenishing mechalllSliLfOI looms of the kind referred to comprising in combination a transferrer having, aprojection thereon, a pin fnormally adapted to engage said projection, a swivel carrying said pin so that on rotation it will. actuate said transferrer, a collar upon said pin, a spring engaging said collar upon one side and a detector engaging said collar :upon the other vside and movable by the vshuttlewhen vthe latter is not properly positioned in the shuttle box to disengage from saidvcollar and permit the spring to'move said pin so that it, shall not engage the transferrer, v y

In testimony whereof I have signed mV name in this specification.
